The present invention relates to the engine speed down during heavy internal combustion engine system, in particular, in a system, the engine restart request in the engine is controlled so as to stop after the crankshaft speed (engine speed) decreased during restart execution engine restart control unit to drive the starter pinion move to ring in order to make the small gear, the gear engaged with the ring gear and pinion rotation, to start the engine. The detector detects the value of engine speed after performing engine reset control after engine speed drops. The predictor predicts the future value of engine speed based on the detection value of engine speed when the engine is reset. A determiner determines whether or not the engine reset has been successful or failed based on the relationship between the detection value of the engine speed and the predicted future value of the engine speed.
